Thanks for the quick respose..I modified the rule now to -
package org.drools.examples;
import org.drools.examples.templates.DBSubscription;
import org.drools.examples.templates.Event;
global java.util.List list
global org.drools.examples.Processor processor;$x : DBSubscription(report == $event.report) from processor.getUsers()
rule "Rule1"
when
$event : Event(eventId == "eventId.IR.001")
then
list.add($x);
end
Still facing some issue, Looking into it
Exception in thread "main" [Error: unbalanced braces ( ... )]

What is Processor? Doesn't look like it is a bound variable. Is it from DBSubscription?

Hi,
I am using the from clause of drools and have written the following expression -
rule "Rule1"
when
$event : Event(eventId == "eventId.IR.001"),
$dbS : DBSubscription( report == $event.report ) from Processor.getUsers()
then
list.add($dbS);
Here processor.getUsers writtens me a list of DBSubscription, When I load this package using
builder.addPackageFromDrl( source );
I get an error saying -
Exception in thread "main" org.drools.compiler.DroolsParserException: Unknown error while parsing. This is a bug. Please contact the Development team.

Would Appreciate any help on the same.
thanks
